The UCAR Research Applications Laboratory (RAL) has released Nujan version 1.4.1. Nujan is a pure Java writer for HDF5 and NetCDF4 files. Nujan is 100% open source and is released under the MIT license. Nujan is intended to be useful in situations where portability and a simplified development process are more important than access to the complete HDF5 feature set.
The only change in version 1.4.1 from version 1.4 is fixing a memory leak related to compression.
Nujan creates files compatible with:
- HDF5 1.8.5 and later
- NetCDF 4.1.1 and later
The primary differences between Nujan and the existing JNI-based HDF5 Java writer are:
- Nujan does not depend on any C code, so does not use the JNI (Java Native Interface)
- The Nujan writer only writes new files. It does not update existing files.
Nujan supports most of the commonly used features of NetCDF4 and HDF5, but does not implement all features. For details and to download Nujan:

With the new netcdf version (4.3.21), does this deprecate the Nujan library?

Hi Dan,
The netCDF-Java library and Nujan library are separate libraries developed by separate teams (netCDF-Java at Unidata, Nujan at RAL). It looks like the Nujan jar has not been updated since April of 2012, so I'd enquire with the Nujan developers to see what the status is with that package (ral.ucar.edu/~steves/nujan.html).
Cheers,
Sean
